DEVELOPING APPARATUS.

To all whom itmay concern:

Be it known that I, GEORGE C. BEIDLER, a

, citizen of the United States of America, residing at Oklahoma, in'the county of Oklahoma, Oklahoma, have invented certain new 111 my patent No. 810,388 and my pending application, Serial Number 310,732 and more especially the latter, although it is to be understood that it can be employed with any developing apparatus.

It has been found in practice that the continuous cords or bands employed with an apron for conveyin the film, or severed film, leave upon thefi m a mark along its edge which is a disadvantage to the finished It has also been found that the developing fluids through which the cords or hands pass tend todestroy said cords or By ractical experience it has been found that tiiese disadvantages are obviated by usin linked chains, more especially chains fbrmed or made of brass. chains have been found to give a better gripping surface and do not obstruct the free flow 'of the de eloping fluid on the film.

This is accounted for 1n viewfof the fact that the contacting surface of the chain is interrupted, which interruption is caused or effected by the natural arrangement of the links. This interruption of the chain is further enhanced by recesses or depressions formed in the contactin surfaces of the chain.

surfaces to a minimum.

These recesses IGClIlCG the contacting It-is an object of this invention to roduce a device of the character noted which will possess advantages in points of simplicity, efficiency and durability proving at the same time comparatively inexpensive to manufacture.

With the foregoing and other objects in View the invention consists in the details of 7 construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

I In describing the invention in detail refcrence Willi-be had to the accompanying Specification of Letters Patent. Application filed October 16,

.a detail of the invention.

These f Patented Nov. 17, 1908. 1906. Serial No. 839,196.

wherein like characters denote corresponding parts in the several views, in which- Figure l, is a fragmentary view of the developing apparatus showing the invention applied thereto. Fig. 2,.is an enlarged detail viewshowing the invention.

In the drawings 1, indicates the compartment for containing the developing fluid and 2, the apron passing therethrough for con-' veying the severed portions of the film. Traveling with said apron through the compartment and contacting with the severed films are the brass link chains 3, which form the feature of this invention. These chains are arranged adjacent the edges of the apron. Itis to be observed in the detail View that the contacting surface of this chain is interrupted and permits the free flow of the developing fiuid entirely across the film. The construction of the chain is such in itself to permit this free flow of the developing fluid, but to further enhance the same, the contacting portions of the chain are provided with rece$es or de ressions 4, which reduce the contacting sur aces of the chains to a minimum.

While but one form of the chain has been illustrated it is to be understood thatany work with the facility desired, the essential feature being that brass being used in the construction of said chain the developing fluid will not attack .the brass or impair its usefulness.

Having fully described my invention what ters Patent, is Y 1. In combination with a developing compartment an apron passing therethrough adapted to carry film, andlinked chains traveling therewith, the surfaces of the chains being interrupted.

2. In a photographic and developing'apparatus, chains in combination with other clalm as new and desire to secure .by Letmeans for conveying film through the developing fluids, those portions of the chains contacting with the film being recessed.

3. In combination with a developing a paratus, an apron passing therethroug 1,

adapted to carry a film and a flexible means acting in conjunction with the apron; said flexible means having the surface contacting 5 with the film interrupted.

4. In combination with a device for con-- drawings forming part of this specification Fig. 3, is

arm of. chain may be employed that will veying prints or films, members comprising loosely connected parts coacting wlth the conveying device for retaining the prints or films on the conveying device, the surfaces 5; of the members contacting the prints or films being interrupted.

5. In'a developing apparatus, an apron for carrying film through developing fluid, and a member engaging the film to hold it on the apr0n,'said member having holes 10 therein.

In testimony whereof I afiix my signature in the resence of two witnesses this 3rd day of ctober, 1906.
